In　the　people　-　vehicles　-　road　-　environment　system,　road　surface　roughness　is　one　of　the　main　factors　which　may　affect　ride　comfort　and　driving　safety.　moreover,　in　recent　years　the　new　research　trend　of　asphalt　pavement　performance　is　inclined　to　emphasize　human　factor.　In　this　study,　applying　the　instruments　such　as　driving　simulation　module,　electrocardiogram　device　and　laser　multi-function　road　detection　equipment,　simulation　studies　on　asphalt　pavement　surface　roughness　were　done　indoors　and　field　tests　were　also　done　by　the　combination　of　electrocardiogram　device　and　assembled　laser　detection　equipments.　The　purpose　of　this　research　is　to　seek　the　physiological-psychological　indictors　which　are　affected　apparently　by　asphalt　pavement　roughness.　The　test　results　testify　that　some　HRV　indicators　are　indeed　affected　by　road　surface　roughness.　So　it　is　practical　that　a　re-evaluation　system　on　asphalt　pavement　roughness　which　is　mainly　based　on　passengers＇　physiological-psychological　reaction　will　be　established　and　a　more　humane　and　reasonable　technical　support　will　be　provided　for　maintenance　and　management　of　road.
